Indicadores da qualidade para sustentabilidade de obras de edificações: banco de dados e valores de referência

The construction sector has an important role in the global economy, but it is one of those that cause more environmental impacts. The sector has been concerned to sustainability issues and has used performance measurement and sustainability indicators to assist the environmental performance improvement. In Brazil, since 2012, the SIAC regulation of the Brazilian Program for Productivity and Quality of the Built Environment - PBQP-H started to require the collection of six sustainability indicators: waste generation throughout and at the end of the construction; water consumption throughout and at the end of the construction; energy consumption throughout and at the end of the construction. However, only the collection of the indicators do not generate performance improvement and reference values to guide the companies' goals. Furthermore, this paper refers to an on-going research which aims to establish a data base and benchmark values for the six PBQP-H sustainability indicators aiming to provide information for construction managers make decisions concerning the environmental quality performance of construction sites. The study was developed from a data survey conducted in seven Brazilian states. The main contributions of this study are the reference values presented for the indicators throughout the construction in each 10% of construction progress and the reference values presented for the indicators at the end of the construction.
